True

Step-by-step explanation:

for every X there can be on Y

that doesn't necessarily go the other way around, but that's not what the problem is asking, so whatever.

Find a formula for the inverse of the function. f(x) = e^6x − 9

STatiana [176]

Answer:

$f^{-1}(x)=\frac{1}{6}\ln(x+9)$

Step-by-step explanation:

So we have the function:

$f(x)=e^{6x}-9$

To solve for the inverse of a function, change f(x) and x, change the f(x) to f⁻¹(x), and solve for it. Therefore:

$x=e^{6f^{-1}(x)}-9$

Add 9 to both sides:

$x+9=e^{6f^{-1}(x)}$

Take the natural log of both sides:

$\ln(x+9)=\ln(e^{6f^{-1}(x)})$

The right side cancels:

$\ln(x+9)=6f^{-1}(x)$

Divide both sides by 6:

$f^{-1}(x)=\frac{1}{6}\ln(x+9)$

And we're done!

Explain how you can divide 6/8 by 0.25. Show the steps to your answer and reply to at least two other responses.

blondinia [14]

Answer:

The result is 3.

Step-by-step explanation:

One way is to convert the 0.25 to a fraction.

Thus 0.25 = 25/100 = 1/4.

Note 6/8 simplifies to 3/4, so we have the division:-

3/4 / 1/4

We invert the 1/4 and multiply:-

= 3/4 * 4/1

= 12/4

= 3 (answer).

Answer:

Option C. is nonlinear.

There is no specified degree in option C's equation, so it is impossible for it to be a linear equation.
